Here’s an awesome video I found of me playing my good friend Stebo in Duke3D… It looks like I’m gonna lose, but I swing it back to victory towards the end to win 10-5! Good times =) Thanks UMK3spaulding for posting the video!
So it seems Ubuntu 12.04 uses a local DNS server for all connections, regardless what you specify in Network Manager.
The easiest way to fix this is edit the following file:
Remove the dnsmasq line, save, and reboot! Your settings will now be fetched from DHCP or taken manually from Network Manager again!
This article will guide you on how to install Dropbox as a service on Linux. First things first, let’s get Dropbox downloaded and installed on our server. To start, paste the following in your terminal…
For 32-bit:
For 64-bit:
After that’s complete, run the dropboxd command:
Next, You’ll see something like this…
Click that link, login with your credentials to link your new dropboxd service to your account. Shortly after, the message above should stop spamming and say that it is now linked! Hit CTRL+C to quit.
The last thing we need to do is enable a init.d script to boot at runtime.
First, determine your current runlevel:
So our current runlevel is 2. Let’s add it correctly though by adding a new “dropboxd” file in /etc/init.d. The only thing you need to modify in the script below is the DROPBOX_USERS variable.
Now that the script resides in init.d, let’s change folders to /etc/rc2.d (our runlevel) and make a symlink from ../init.d/dropboxd to the present working dir.
That’s it! You can call it with the service command, or just execute it from /etc/init.d or /etc/rc2.d.
I recently upgraded to Ubuntu 12.04 but found myself super frustrated to see my laptop lockup immediately after logging in via the GUI. It turned out to be an issue with the intel driver and dual monitors…
There was reported success by downgrading xserver-xorg-input-evdev, with the version you can find here:
https://launchpad.net/~sarvatt/+archive/sru1/+build/3118994
It works! I now have dual monitors again!

Few commands I use often in HP-UX; Coming from over 15 years of Linux experience, the quirks in HP-UX can get annoying at first, but hopefully this will help you through it!
Sick of your backspace key not working? Here’s your answer:
Annoyed with the shitty output of df?
Trying to figure out what the model/arch of the server is?
This lists a few different thing… disk related, and/or fibre channel cards:
How do I configure which mirror to boot from!?
I miss yum/apt-get:
The \* is pretty cool, it prevents the TUI/GUI from loading, but continues the install/dep check. Makes it feel more like yum or apt-get, instead of aptitude or a GUI update manager.
AHHH usermod and passwd are missing flags in HP-UX! No, just use modprpw instead!
This will reset the expiration of a locked account.
Where the fuck are the init.d and rc scripts?!
How can I figure out the current runlevel?!
I miss bash, how can I auto-complete a command?!
WTF?! No history command?!?! Lies, hit esc+k – then use j/k to cycle forward/backwards respectively. To edit a line you scroll to, it’s interactive vi in ksh… so ‘l’ to move foward, shift+R to replace, etc…
Here are my notes on how to remove and replace a dead mirrored drive on HP-UX 11i v3:
Remove bad mirrored boot disk HP-UX:
Check for stale LEs:
Next we need to remove the bad drive from the LVM, so let’s reduce the lvols (the last integer is the key from the last lvdisplay command):
Now that we’ve reduced the mirror, let’s remove partition 2 from the volgroup:
If we can’t reduce because it’s critically failed, then we need to do this:
Then confirm:
Here’s an example of a DEAD drive from ioscan:
Example of REPLACED drive with the old DEAD DSF – Map DSF then Re-add to VG:
STEP1: In order to see the new drive, you need to do this first (AFTER NEW DRIVE IS INSERTED): scsimgr replace_wwid –D /dev/rdisk/disk62
STEP2: Formart disk219
STEP3: Then you can map the new DSF to the old one:
STEP4: Make Bootable and fix EFI partitions:
STEP5: Create PV, Extend VG, and Extend LVs:
STEP6: Verify VG and boot paths
If the mirrored disk fails to boot from EFI, boot off the alternate working one, and re-execute setboot -v with the device path (even though it might already be set, set it again since the wwid change).
One of my clients needed to expand their DB since it was at 96% utilization. Thankfully, it was already in a volume group. Here are the steps I took to add a new LUN to the VG and expand it.
First, use fdisk to find the new LUN that doesn’t have a partition table and then use fdisk to create a new partition on it as Linux LVM:
Now that the partition table is setup correctly, let’s create a new LVM on the drive, and extend our existing volume group using the new physical LUN.
Here you can see our physical extents has increased due to the addition of the new physical drive to the volume group:
I only wanted to allocated ~75% of the new LUN to lvol_d03, so I took the Current LE 23968 from the previous lvdisplay. I prefer to actually distribute via Extents, rather than the easy way of +G, etc. So I added 9827 extents (from a total of 12827 free) to the existing 23968, totaling 33795:
Above you can see we still have 3000 extents available. I tend to leave a little as wiggle room so if we ever get into a position of running out of space we aren’t screwed.
Now that LVM has extended the volume group, we need to have the filesystem recognize it:
(This box didn’t have ext3online (older kernel; 2.6.9), so just decided to do it the old school way…)
That’s it, now the moment of truth…
Woot, all good! (749GB to 1.1TB)
Thought this might be helpful:
or if you have an HP storage array (EVA, etc)
Then just do fdisk -l to see if it’s presented or not!

Please don’t do this on any production boxes, lol.
